Sonnax hydraulic line pressure booster kits contain stronger pressure regulator springs and large ratio boost valves designed to work together, providing progressive pressure increases as driving conditions become more demanding. Their springs are approximately 10 percent stronger than OEM and more conservative in impact than other aftermarket kit springs. Large ratio boost valves provide higher pressure incrementally and when it's needed the most. The combination of these springs and valves in the Sonnax hydraulic line pressure booster kits gives you the best of both worlds--a modest pressure increase at the low-end, with a high-end pressure that's equal to or greater than that of other aftermarket kit springs.

Summit Racing™ Governor recalibration kits allow you to raise or lower, relative to vehicle speed, the points where your transmission shifts. This is accomplished by a system of combining a variety of weights and springs in your governor, modifying the vehicle speed signal your transmission's shift valves receive. These kits can greatly improve the peak performance and enhance the drivability of the vehicle. They are very useful for transmission swaps, or if you have a car that is very light or has a low rear gear ratio. These kits also work great for bracket cars retaining an automatic 1-2 shift.

Sonnax Line pressure booster kits allow you to shift aggressively and then feel the tranny grab the clutches with more power when it changes gear. The larger boost valves and matching regulator springs raise line pressure progressively as higher pressure is commanded. These kits modify the sensor signal, which causes the computer to create a pressure increase. They're installed between the pressure sensor and vehicle harness using OE-style sealed connectors; no modifications are needed to the transmission.

Vehicles with a GM 8L45 or 8L90 automatic transmission may exhibit high or low line pressure that results in harsh/soft shifts, burnt clutches, loss of cooler and lube flow, and overheating of the transmission and converter. These problems may be caused by wear of the pressure regulator bore casting at the VFS signal port area and/or at the shuttle valve sleeve. Wear at the inboard port of the pressure regulator bore allows VFS (throttle) signal pressure to leak, preventing proper action of the pressure regulator valve and potentially allowing it to remain in the low line pressure position. Wear of the shuttle sleeve due to continuous oscillation of the shuttle valve creates a path for balance line pressure at the pressure regulator valve to exhaust, resulting in excessive low line pressure. Sonnax drop-in pressure regulator and shuttle valve kits restore hydraulic integrity to the lineup by addressing wear that subjects the transmission to either excessively high or low line pressure with upgraded materials and unique designs. The pressure regulator valve has been designed with a lengthened spring pocket spool at the VFS signal port area, which provides over double the sealing capability to this critical end of the valve and allows it to operate in unworn portions of the bore. The length of the critical shuttle valve diameter has been significantly lengthened to provide better sealing and durability of the assembly. Additional details: * Hardcoat anodized aluminum valves and highly wear-resistant billet aluminum sleeve combat premature wear * Pressure regulator valve VFS signal spool 200 percent longer than OE and operates in unworn area of the bore * Critical shuttle valve spool made 30 percent longer than OE for added sealing and durability * Drop-in Zip Valve parts install quickly and easily Kit contents: * Pressure regulator valve * Spring * Shuttle valve * Shuttle sleeve
